Gulf Park Estates, MS Coastal Erosion Rate
Is the coast eroding 9.7 miles south of Gulf Park Estates, MS?
Nothing alarming measured 9.7 miles south of Gulf Park Estates, MS: whatever shift USGS's transects picked up here is too small to call reliably one way or the other, which this site reports as "no significant trend" rather than forcing a direction.
What this reading actually covers
Gulf Park Estates, MS is the nearest named place, 9.7 miles away, to a ~3.5-mile stretch of coast USGS has surveyed - the reading below covers that whole stretch, not a single property in it. Segment center: 30.25, -88.70. The survey behind it runs to 2001, in USGS's Gulf of Mexico assessment, using the LRR method. Shoreline surveys aren't repeated every year, so this is the most recent long-term measurement USGS has published for this coast, not a live reading.
How solid is this number
This reading comes from 87 individual transects averaged together, 47% of which measured erosion rather than growth. The published margin on this reading runs ±3.09 ft/yr. The unadjusted figure here, 0.24 ft/yr, would place it 944 of 1211 if ranked directly - but an unreliable rank isn't a useful one, which is exactly why "no significant trend" is the headline instead. Source: USGS Open-File Report 2004-1089. Rank 1183 nationally for growth belongs to Quinby, VA, 897 miles from this stretch, measured at 3.21 ft/yr. Gulf Park Estates, MS, 1.6 miles off, is the adjacent measured stretch, itself no significant trend.
